Twelve tips for designing and implementing an academic coaching program.

Coaching has become increasingly popular as a mechanism to support learning across the health professions education (HPE) continuum. While there is a growing body of literature in this area, there is minimal guidance related to the design and implementation of academic coaching in health professional courses. This paper seeks to contribute to this literature by presenting guidance for academic developers who are considering introducing academic coaching into a health professional course. The 12 tips are based on the authors' collective experiences of designing and implementing academic coaching in university medical courses in Australia and the UK. Although focused on medical education, this paper is intended to have applicability across the health professions, and potentially across university and postgraduate training contexts. Together, the tips offer a strategic and operational framework to guide the design and implementation of academic coaching initiatives in health professions education.

Student assistantship programme: an evaluation of impact on readiness to transit from medical student to junior doctor.

BACKGROUND: Studies report that medical graduates are not prepared for practice as expected, and interventions have been developed to prepare them for practice. One such intervention is the assistantship, which provides hands-on opportunities to hone clinical skills and undertake responsibilities under supervision. The Lee Kong Chian School of Medicine (LKCMed) is Singapore's newest medical school, and students undergo a Student Assistantship Programme (SAP) to prepare for practice as junior doctors (PGY1). This study evaluated the SAP from the students' and clinical supervisors' perspectives. METHODS: Students completed online questionnaires to assess readiness for practice before and after SAP, and a subsample were interviewed about their experiences of SAP and its impact on their preparedness for PGY1. In addition, after our graduates had begun work as PGY1 doctors, their clinical supervisors completed an online questionnaire and were interviewed about the perceived benefits of SAP and the attributes of our graduates as junior doctors. RESULTS: Fifty (96%) students completed the pre-SAP questionnaire and 46 (92%) completed the post-SAP questionnaire. Levels of preparedness increased post-SAP (mean scores range pre-SAP: 2.38 to 4.32 vs post-SAP: 3.08 to 4.48); so did opportunities to undertake PGY1 duties (pre-SAP: 56% vs post-SAP: 96%), and hands-on experience in medical emergencies (pre-SAP: 76% vs post-SAP: 89%).Experience of acute care situations increased except "paracetamol overdose". Readiness to be first respondents in ten acute situations improved (statistically significant for asthma, chronic obstructive pulmonary disease exacerbation, gastrointestinal bleed, sepsis, and adverse drug reactions). Three themes emerged from twenty-five student interviews: learning about the work environment, opportunities to learn in a safe environment, and enhancing SAP for future students. Thirty-three supervisors completed the questionnaire, and 70% rated SAP positively in preparing students for PGY1. Eight supervisors interviewed shared positively about the content, timing, and duration of SAP; and suggested future SAPs help students to develop coping and reflective skills. CONCLUSIONS: The SAP improved students' preparedness and experience across clinical areas, and students felt the SAP helped bridge undergraduate curriculum and work, provided opportunities to hone their skills and learn from junior doctors. Most clinical supervisors rated the SAP effective in preparing students for PGY1. This is the first formal evaluation of an assistantship in Singapore, and the findings are encouraging from the perspective of students and PGY1 supervisors.

Role of social comparison in preparedness for practice as a junior doctor in Singapore: a longitudinal qualitative study.

OBJECTIVES: To date, most research on medical graduates' preparedness for practice has conceptualised preparedness as something possessed by the individual. However, new doctors work within social settings with other people and, given this, we argue that preparedness has a social and comparative dimension. The aim of this paper is to explore medical students'/graduates' self-assessments of their preparedness for practice using the lens of social comparison theory. SETTING: We invited medical students from one of Singapore's three medical schools who were in their final-year Student Assistantship Programme to participate in semi-structured interviews, and follow-up interviews 6 months later when they were working as junior doctors. Data was collected from two cohorts, in 2018 and 2019. Initial analysis of interview transcripts was inductive and thematic. Social comparison theory was used for subsequent theory-driven analysis. PARTICIPANTS: 31 participants took part, of whom 21 also engaged in follow-up interviews. RESULTS: We identified three uses of social comparison: as coping strategy to manage uncertainties in transitions where there was no formal, objective testing of their performance; as a means to confirm their self-perceived preparedness (upwards or downwards, eg, being better or worse prepared than comparator others); and as the basis for decision-making (eg, changing career choices). CONCLUSIONS: Senior medical students and newly-graduated doctors compare themselves with peers and near-peers in terms of prior learning and current performance to evaluate and understand their own performance at work. Future studies need to examine further how the feeling of preparedness or unpreparedness generated from social comparisons may affect subsequent clinical performance and professional development.

Exploring the feasibility of using very short answer questions (VSAQs) in team-based learning (TBL).

BACKGROUND: Team-based learning (TBL) currently relies on single best answer questions (SBAQs) to provide immediate feedback. Very short answer questions (VSAQs) are a reliable and discriminatory alternative that encourage learners to use more authentic clinical reasoning strategies compared to SBAQs. However, the challenge of marking VSAQs has limited their integration into TBL; we therefore explored the feasibility of VSAQs within a TBL session. METHODS: An online platform was developed to allow immediate marking of VSAQs during the TBL sessions. As part of the readiness assurance process, students completed VSAQs and SBAQs, which were marked in real time. RESULTS: Instructors were able to mark all VSAQs during the individual readiness assurance test (iRAT), which facilitated the provision of immediate feedback during the team readiness assurance test (tRAT). The mean time to mark five VSAQs was 422 seconds (SD 73 seconds). For VSAQs, the number of attempts to reach the correct answer ranged from 1 to 38, compared to 1 to 4 for SBAQs. In total, 71.6% of students agreed that using VSAQs in TBL helped to emphasise group discussions. DISCUSSION: The wide range of attempts at, and students' perspectives of VSAQs are suggestive of their positive impact on student discussion during TBL. We demonstrate how new technology allows VSAQs to be feasibly integrated into TBL with the potential to enrich group discussions.

Promotion of knowledge transfer and retention in year 2 medical students using an online training exercise.

It was recently shown that novice medical students could be trained to demonstrate the speed-to-diagnosis and diagnostic accuracy typical of System-1-type reasoning. However, the effectiveness of this training can only be fully evaluated when considering the extent to which knowledge transfer and long-term retention occur as a result, the former of which is known to be notoriously difficult to achieve. This study aimed to investigate whether knowledge learned during an online training exercise for chest X-ray diagnosis promoted either knowledge transfer or retention, or both. Second year medical students were presented with, and trained to recognise the features of four chest X-ray conditions. Subsequently, they were shown the four trained-for cases again as well as different representations of the same conditions varying in the number of common elements and asked to provide a diagnosis, to test for near-transfer (four cases) and far-transfer (four cases) of knowledge. They were also shown four completely new conditions to diagnose. Two weeks later they were asked to diagnose the 16 aforementioned cases again to assess for knowledge retention. Dependent variables were diagnostic accuracy and time-to-diagnosis. Thirty-six students volunteered. Trained-for cases were diagnosed most accurately and with most speed (mean score = 3.75/4, mean time = 4.95 s). When assessing knowledge transfer, participants were able to diagnose near-transfer cases more accurately (mean score = 2.08/4, mean time = 15.77 s) than far-transfer cases (mean score = 1.31/4, mean time = 18.80 s), which showed similar results to those conditions previously unseen (mean score = 0.72/4, mean time = 19.46 s). Retention tests showed a similar pattern but accuracy scores were lower overall. This study demonstrates that it is possible to successfully promote knowledge transfer and retention in Year 2 medical students, using an online training exercise involving diagnosis of chest X-rays, and is one of the few studies to provide evidence of actual knowledge transfer.

COVID 19: Designing and conducting an online mini-multiple interview (MMI) in a dynamic landscape.

Introduction: The COVID-19 pandemic presented numerous, significant challenges for medical schools, including how to select the best candidates from a pool of applicants when social distancing and other measures prevented "business as usual" admissions processes. However, selection into medical school is the gateway to medicine in many countries, and it is critical to use processes which are evidence-based, valid and reliable even under challenging circumstances. Our challenge was to plan and conduct a multiple-mini interview (MMI) in a dynamic and stringent safe distancing context.Methods: This paper reports a case study of how to plan, re-plan and conduct MMIs in an environment where substantially tighter safe distancing measures were introduced just before the MMI was due to be delivered.Results: We report on how to design and implement a fully remote, online MMI which ensured the safety of candidates and assessors.Discussion: We discuss the challenges of this approach and also reflect on broader issues associated with selection into medical school during a pandemic. The aim of the paper is to provide broadly generalizable guidance to other medical schools faced with the challenge of selecting future students under difficult conditions.

Development of a three-dimensional printed heart from computed tomography images of a plastinated specimen for learning anatomy.

Learning anatomy is commonly facilitated by use of cadavers, plastic models and more recently three-dimensional printed (3DP) anatomical models as they allow students to physically touch and hold the body segments. However, most existing models are limited to surface features of the specimen, with little opportunity to manipulate the structures. There is much interest in developing better 3DP models suitable for anatomy education. This study aims to determine the feasibility of developing a multi-material 3DP heart model, and to evaluate students' perceptions of the model. Semi-automated segmentation was performed on computed tomgoraphy plastinated heart images to develop its 3D digital heart model. Material jetting was used as part of the 3D printing process so that various colors and textures could be assigned to the individual segments of the model. Morphometric analysis was conducted to quantify the differences between the printed model and the plastinated heart. Medical students' opinions were sought using a 5-point Likert scale. The 3DP full heart was anatomically accurate, pliable and compressible to touch. The major vessels of the heart were color-coded for easy recognition. Morphometric analysis of the printed model was comparable with the plastinated heart. Students were positive about the quality of the model and the majority of them reported that the model was useful for their learning and that they would recommend their use for anatomical education. The successful feasibility study and students' positive views suggest that the development of multi-material 3DP models is promising for medical education.

Taking the Pressure Off the Patient - Understanding Digital Rectal Examinations on a Real Subject.

Better understanding of palpation techniques during unsighted physical examinations has mostly been limited to qualitative and quantitative studies of performance of experts whilst conducting examinations on plastic benchtop models. However, little is known about their performance when conducting such examinations on real subjects. OBJECTIVE: The aim of this paper is to better understand palpation techniques of experts whilst conducting a Digital Rectal Examination on a real subject. METHODS: We recruited four consultants from relevant specialties and asked them to conduct two DREs on a Rectal Teaching Assistant whilst wearing small position and pressure sensors on their examining finger. We segmented the relevant anatomy from an MRI taken of the pelvic region, registered 3D models and analysed retrospectively performance in relation to executed tasks, supination/pronation, palpation convex hull and pressure applied. RESULTS: Primary care consultants examined the anatomy more holistically compared to secondary care experts, the maximum pressure applied across experiments is 3.3N, overall the pressure applied on the prostate is higher than that applied to rectal walls, and the urologist participant not only applied the highest pressure but also did so with the highest most prominent frequency (15.4 and 25.3 Hz). CONCLUSIONS: The results of our research allow for better understanding of experts' technical performance from relevant specialities when conducting a DRE, and suggest the range of pressure applied whilst palpating anatomy. SIGNIFICANCE: This research will be valuable in improving the design of haptics-based learning tools, as well as in encouraging reflection on palpation styles across different specialities to develop metrics of performance.

Team-Based Learning Analytics: An Empirical Case Study.

Many medical schools that have implemented team-based learning (TBL) have also incorporated an electronic learning architecture, commonly referred to as a learning management system (LMS), to support the instructional process. However, one LMS feature that is often overlooked is the LMS's ability to record data that can be used for further analysis. In this article, the authors present a case study illustrating how one medical school used data that are routinely collected via the school's LMS to make informed decisions. The case study started with one instructor's observation that some teams in one of the undergraduate medical education learning modules appeared to be struggling during one of the team activities; that is, some teams seemed unable to explain or justify their responses to items on the team readiness assurance test (tRAT). Following this observation, the authors conducted 4 analyses. Their analyses demonstrate how LMS-generated and recorded data can be used in a systematic manner to investigate issues in the real educational environment. The first analysis identified a team that performed significantly poorer on the tRAT. A subsequent analysis investigated whether the weaker team's poorer performance was consistent over a whole module. Findings revealed that the weaker team performed poorer on the majority of the TBL sessions. Further investigation using LMS data showed that the weaker performance was due to the lack of preparation of one individual team member (rather than a collective poor tRAT performance). Using the findings obtained from this case study, the authors hope to convey how LMS data are powerful and may form the basis of evidence-based educational decision making.

Summative and Formative Style Anatomy Practical Examinations: Do They Have Impact on Students' Performance and Drive for Learning?

Anatomical knowledge is commonly assessed by practical examinations that are often administered in summative format. The format of anatomy practical examination was changed at the Lee Kong Chian School of Medicine in Singapore from summative (graded; must pass) to formative (ungraded; no pass/fail) in academic year (AY) 2017-2018. Both assessment formats were undertaken online, but the formative mode used a team-based learning activity comprising individual and team assessments. This gave an unique opportunity to investigate: (1) the impact of two different online assessment formats on student performance in practical examination; (2) the impact of new formative practical examination on students' performance in summative examinations; and (3) students' opinions of these two practical examination formats. The class of 2021 perceptions was obtained as they experienced both formats. A retrospective cohort study was also conducted to analyze the Year 2 students' performance in anatomy practical and year-end summative examinations of cohorts AY 2015-2016, AY 2016-2017 (summative format), and AY 2017-2018 (formative format). There were no significant differences in students' performance between two practical examination formats. The cohort who experienced the formative format, performed significantly better in summative examinations (mean ± SD: 82.32 ± 10.22%) compared with the cohort who experienced the summative format (73.77 ± 11.09%) (P < 0.001). Students highlighted positive features of the formative practical examination, including team reinforcement of learning, instant feedback, and enhanced learning. These findings indicate that students continue to study for anatomy practical examination without the need for external drivers. The team-based learning style practical examination enhances students' performance in summative examinations.

Health professions digital education on clinical practice guidelines: a systematic review by Digital Health Education collaboration.

BACKGROUND: Clinical practice guidelines are an important source of information, designed to help clinicians integrate research evidence into their clinical practice. Digital education is increasingly used for clinical practice guideline dissemination and adoption. Our aim was to evaluate the effectiveness of digital education in improving the adoption of clinical practice guidelines. METHODS: We performed a systematic review and searched seven electronic databases from January 1990 to September 2018. Two reviewers independently screened studies, extracted data and assessed risk of bias. We included studies in any language evaluating the effectiveness of digital education on clinical practice guidelines compared to other forms of education or no intervention in healthcare professionals. We used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach to assess the quality of the body of evidence. RESULTS: Seventeen trials involving 2382 participants were included. The included studies were diverse with a largely unclear or high risk of bias. They mostly focused on physicians, evaluated computer-based interventions with limited interactivity and measured participants' knowledge and behaviour. With regard to knowledge, studies comparing the effect of digital education with no intervention showed a moderate, statistically significant difference in favour of digital education intervention (SMD = 0.85, 95% CI 0.16, 1.54; I2 = 83%, n = 3, moderate quality of evidence). Studies comparing the effect of digital education with traditional learning on knowledge showed a small, statistically non-significant difference in favour of digital education (SMD = 0.23, 95% CI - 0.12, 0.59; I2 = 34%, n = 3, moderate quality of evidence). Three studies measured participants' skills and reported mixed results. Of four studies measuring satisfaction, three studies favoured digital education over traditional learning. Of nine studies evaluating healthcare professionals' behaviour change, only one study comparing email-delivered, spaced education intervention to no intervention reported improvement in the intervention group. Of three studies reporting patient outcomes, only one study comparing email-delivered, spaced education games to non-interactive online resources reported modest improvement in the intervention group. The quality of evidence for outcomes other than knowledge was mostly judged as low due to risk of bias, imprecision and/or inconsistency. CONCLUSIONS: Health professions digital education on clinical practice guidelines is at least as effective as traditional learning and more effective than no intervention in terms of knowledge. Most studies report little or no difference in healthcare professionals' behaviours and patient outcomes. The only intervention shown to improve healthcare professionals' behaviour and modestly patient outcomes was email-delivered, spaced education. Future research should evaluate interactive, simulation-based and spaced forms of digital education and report on outcomes such as skills, behaviour, patient outcomes and cost.

A Psychological Foundation for Team-Based Learning: Knowledge Reconsolidation.

Although team-based learning is a popular instructional approach, little is known about its psychological foundation. In this Perspective, the authors propose a theoretical account of the psychological mechanisms through which team-based learning works. They suggest a knowledge reconsolidation hypothesis to explain how the distinct phases of team-based learning enable students to learn. Knowledge reconsolidation is the process whereby previously consolidated knowledge is retrieved from memory with the purpose of actively consolidating it again. Reconsolidation aims to preserve, strengthen, and adjust knowledge that is already stored in long-term memory. This process is generally considered an important reason why people who reactivate what they have previously learned many times develop knowledge structures that are extremely stable and easily retrieved.The authors propose that 4 psychological mechanisms enable knowledge reconsolidation, each of which is tied to a distinct phase of team-based learning: retrieval practice, peer elaboration, feedback, and transfer of learning. Before a team-based learning session, students engage in independent, self-directed learning that is often followed by at least one night of sleep. The latter is known to facilitate synaptic consolidation in the brain. During the actual team-based learning session, students are first tested individually on what they learned, then they discuss the answers to the test with a small group of peers, ask remaining "burning questions" to the teacher, and finally engage in a number of application exercises.This knowledge reconsolidation hypothesis may be considered a framework to guide future research into how team-based learning works and its outcomes.

Digital Problem-Based Learning in Health Professions: Systematic Review and Meta-Analysis by the Digital Health Education Collaboration.

BACKGROUND: The use of digital education in problem-based learning, or digital problem-based learning (DPBL), is increasingly employed in health professions education. DPBL includes purely digitally delivered as well as blended problem-based learning, wherein digital and face-to-face learning are combined. OBJECTIVE: The aim of this review is to evaluate the effectiveness of DPBL in improving health professionals' knowledge, skills, attitudes, and satisfaction. METHODS: We used the gold-standard Cochrane methods to conduct a systematic review of randomized controlled trials (RCTs). We included studies that compared the effectiveness of DPBL with traditional learning methods or other forms of digital education in improving health professionals' knowledge, skills, attitudes, and satisfaction. Two authors independently screened studies, extracted data, and assessed the risk of bias. We contacted study authors for additional information, if necessary. We used the random-effects model in the meta-analyses. RESULTS: Nine RCTs involving 890 preregistration health professionals were included. Digital technology was mostly employed for presentation of problems. In three studies, PBL was delivered fully online. Digital technology modalities spanned online learning, offline learning, virtual reality, and virtual patients. The control groups consisted of traditional PBL and traditional learning. The pooled analysis of seven studies comparing the effect of DPBL and traditional PBL reported little or no difference in postintervention knowledge outcomes (standardized mean difference [SMD] 0.19, 95% CI 0.00-0.38). The pooled analysis of three studies comparing the effect of DPBL to traditional learning on postintervention knowledge outcomes favored DPBL (SMD 0.67, 95% CI 0.14-1.19). For skill development, the pooled analysis of two studies comparing DPBL to traditional PBL favored DPBL (SMD 0.30, 95% CI 0.07-0.54). Findings on attitudes and satisfaction outcomes were mixed. The included studies mostly had an unclear risk of bias. CONCLUSIONS: Our findings suggest that DPBL is as effective as traditional PBL and more effective than traditional learning in improving knowledge. DPBL may be more effective than traditional learning or traditional PBL in improving skills. Further studies should evaluate the use of digital technology for the delivery of other PBL components as well as PBL overall.

Effects of graded versus ungraded individual readiness assurance scores in team-based learning: a quasi-experimental study.

Pre-class preparation is a crucial component of team-based learning (TBL). Lack of preparation hinders both individual learning and team performance during TBL. The purpose of the present study was to explore how the grading of the individual readiness assurance test (iRAT) can affect pre-class preparation, iRAT performance and performance in the end-of-year examination. Using a quasi-experimental design, Year 1 and 2 students' download frequency for their pre-class materials, performance on iRAT and examination were examined under two conditions; (1) under which the iRAT was graded and (2) under which the iRAT was ungraded. Medical students (N = 220) from three cohorts were included in the study. Differences between both conditions were tested by means of six separate ANCOVAs, using medical school entry test scores as the covariate to account for potential cohort effects. Results revealed that students were downloading more pre-class materials prior to their TBL sessions, and were performed significantly better on iRAT when their performance was graded, even after controlling for cohort effects. Analysis of covariance demonstrated that performance on iRAT also appeared to affect performance on their examination scores. The results of the study suggest that grading has a positive effect on students' iRAT scores. Implications for TBL are discussed.

Evidence supporting dual-process theory of medical diagnosis: a functional near-infrared spectroscopy study.

PURPOSE: The objective of this study was to determine the extent to which the dual-process theory of medical diagnosis enjoys neuroscientific support. To that end, the study explored whether neurological correlates of system-2 thinking could be located in the brain. It was hypothesised that system-2 thinking could be observed as the activation of the prefrontal cortex. METHOD: An experimental paradigm was applied that consisted of a learning and a test phase. During the learning phase, 22 medical students were trained in diagnosing chest X-rays. Four of these eight cases were presented repeatedly, to develop a high level of expertise for these cases. During the test phase, all eight cases were presented and the participants' prefrontal cortex was scanned using functional near-infrared spectroscopy. Response time and diagnostic accuracy were recorded as behavioural indicators. RESULTS: The results revealed that participants' diagnostic accuracy in the test phase was significantly higher for the trained cases as compared with the untrained cases (F[1, 21] = 138.80, p < 0.001, η2  = 0.87). Also, their response time was significantly shorter for these cases (F[1, 21] = 18.12, p < 0.001, η2  = 0.46). Finally, the results revealed that only for the untrained cases, could a significant activation of the anterolateral prefrontal cortex be observed (F[1, 21] = 21.00, p < 0.01, η2  = 0.34). CONCLUSION: The fact that only untrained cases triggered higher levels of blood oxygenation in the prefrontal cortex is an indication that system-2 thinking is a cognitive process distinct from system 1. Implications of these findings for the validity of the dual-process theory are discussed.

Real-time Visualisation and Analysis of Clinicians' Performance during Palpation in Physical Examinations.

OBJECTIVE: Motivated by the fact that palpation skills are challenging to learn and teach, particularly during Digital Rectal Examinations (DRE), and the lack of understanding of what constitutes adequate performance, we present a visualisation and analysis system that uses small position and pressure sensors located on the examining finger, allowing the quantitative analysis of duration, steps and pressure applied. METHODS: The system is first described, followed by an experimental study of twenty experts from four clinical specialties performing ten DREs each on a benchtop model using the proposed system. Analysis of the constitutive steps was conducted to improve understanding of the examination. A Markov model representing executed tasks and analysis of pressure applied is also introduced. RESULTS: The proposed system successfully allowed the visualisation and analysis during the experimental study. General Practitioners and Nurses were found to execute more tasks compared to Urologists and Colorectal Surgeons. Urologists executed the least number of tasks and were the most consistent group compared to others. CONCLUSION: The ability to "see through" allowed us to better characterise the performance of experts when conducting a DRE on a benchtop model, comparing the performance of relevant specialties, and studying executed tasks and the pressure applied. The Markov model presented summarises task execution of experts and could be used to compare performance of novices against that of experts. SIGNIFICANCE: This approach allows for the analysis of performance based on continuous sensor data recording that can be easily extended to real subjects and other types of physical examinations.

Implementation of team-based learning on a large scale: Three factors to keep in mind.

Team-based learning (TBL) is a structured form of small group learning that can be scaled up for delivery in large classes. The principles of successful TBL implementation are well established. TBL has become widely practiced in medical schools, but its use is typically limited to certain courses or parts of courses. Implementing TBL on a large scale, across different courses and disciplines, is the next logical step. The Lee Kong Chian School of Medicine (LKCMedicine), a partnership between Nanyang Technological University, Singapore and Imperial College London, admitted its first students in 2013. This new undergraduate medical program, developed collaboratively by faculty at both institutions, uses TBL as its main learning and teaching strategy, replacing all face-to-face lectures. TBL accounts for over 60% of the curriculum in the first two years, and there is continued learning through TBL during campus teaching in the remaining years. This paper describes our experience of rolling out TBL across all years of the medical curriculum, focusing on three success factors: (1) "team-centric" learning spaces, to foster active, collaborative learning; (2) an e-learning ecosystem, seamlessly integrated to support all phases of the TBL process and (3) teaching teams in which experts in pedagogical process (TBL Facilitators) co-teach with experts in subject matter (Content Experts).

Inducing System-1-type diagnostic reasoning in second-year medical students within 15 minutes.

Purpose: Diagnostic reasoning literature debates the significance of "dual-process theory" and the importance of its constituent types of thinking: System-1and System-2. This experimental study aimed to determine whether novice medical students could be trained to utilize System-1 thinking when making diagnoses based on chest X-rays. Method: Second-year medical students were recruited and presented with a series of eight online chest X-rays cases. Participants were shown half of the cases repeatedly during a training phase and the other half only twice. During the final test phase, they were shown all eight cases, providing a diagnosis as a free text answer. Dependent variables were diagnostic accuracy and response time. Results: Thirty-two students participated. During the test phase, students responses were significantly more accurate and faster for cases which had been seen repeatedly during the training phase (mean score = 3.56/4, mean time = 2.34 s) compared with cases which had been seen only twice (mean score = 1.59/4, mean time = 7.50 s). Conclusion: This study demonstrates that it is possible to induce in novice students the speed-to-diagnosis and diagnostic accuracy typical of System-1-type reasoning. The full experimental design and the chest X-rays used may provide new opportunities to explore some of the issues surrounding dual-process theory.

Evaluation by medical students of the educational value of multi-material and multi-colored three-dimensional printed models of the upper limb for anatomical education.

For centuries, cadaveric material has been the cornerstone of anatomical education. For reasons of changes in curriculum emphasis, cost, availability, expertise, and ethical concerns, several medical schools have replaced wet cadaveric specimens with plastinated prosections, plastic models, imaging, and digital models. Discussions about the qualities and limitations of these alternative teaching resources are on-going. We hypothesize that three-dimensional printed (3DP) models can replace or indeed enhance existing resources for anatomical education. A novel multi-colored and multi-material 3DP model of the upper limb was developed based on a plastinated upper limb prosection, capturing muscles, nerves, arteries and bones with a spatial resolution of ∼1 mm. This study aims to examine the educational value of the 3DP model from the learner's point of view. Students (n = 15) compared the developed 3DP models with the plastinated prosections, and provided their views on their learning experience using 3DP models using a survey and focus group discussion. Anatomical features in 3DP models were rated as accurate by all students. Several positive aspects of 3DP models were highlighted, such as the color coding by tissue type, flexibility and that less care was needed in the handling and examination of the specimen than plastinated specimens which facilitated the appreciation of relations between the anatomical structures. However, students reported that anatomical features in 3DP models are less realistic compared to the plastinated specimens. Multi-colored, multi-material 3DP models are a valuable resource for anatomical education and an excellent adjunct to wet cadaveric or plastinated prosections.
